From the above, it can be seen that the beneficial effects of the present invention are:
1. the fire-resistant layer of the cable uses the ceramic silicon rubber belt and the ceramic silicon rubber insulation to replace the original mica belt, because the mica belt is easy to absorb moisture, the insulation resistance of the moisture-absorbed mica belt is easy to reduce and is not easy to pass a fire-resistant test, and the ceramic silicon rubber belt and the ceramic silicon rubber insulation are not easy to absorb moisture, the insulation resistance is not easy to reduce and is easy to pass the fire-resistant test, the fire-resistant time is long, when the cable burns, the ceramic silicon rubber belt and the insulation form a silicon dioxide shell after burning, the silicon dioxide is also an insulation material with higher insulating property, and the fire-resistant stability of the cable is high. And the fire-resistant layer is also an insulating layer, so that external insulation is omitted, and the outer diameter and the weight of the cable are reduced.
The soft conductor is a soft conductor, the surface of the soft conductor is uneven after the soft conductor is twisted, mica is easy to damage when a common mica tape is wound, once the mica is damaged, the mica tape does not play a fire-resistant role, the mica is thin, the mica is hot when flame burns, the surface temperature of the soft conductor is high, the monofilament of the soft conductor is thin and small in heat capacity, and the monofilament of the soft conductor is easy to burn off, so that the common mica tape is difficult to pass a fire-resistant test on the soft conductor, and the fire-resistant insulation of ceramic silicon rubber can avoid the phenomenon.
2. The high flame-retardant layer adopts ceramic silicon rubber material as the flame-retardant and fireproof layer, the material is silicon rubber when not burning, is soft and high in temperature resistance, becomes silicon dioxide material after burning and becomes a hard silicon dioxide ceramic shell, flame and heat are prevented from entering, the temperature of the cable core is greatly reduced, and the flame-proof and fireproof effects are achieved.
3. The invention adopts the brass band as the metal protective layer, and because the brass band is harder than the common pure copper band and softer than other armor materials, the invention can prevent mice and termites from further biting the cable core after biting the sheath and does not influence the flexibility of the cable.
4. The outer sheath of the invention adopts a special B1-grade halogen-free low-smoke flame-retardant rat-proof and termite-proof sheath material, reduces the smoke amount and combustion heat of the cable, simultaneously the cable has the characteristics of no halogen, low smoke, flame retardance, low toxicity and the like, simultaneously, the total heat emission amount of the cable is low when the cable is combusted, the combustion carbonization height is small, the safety of the rail transit cable in a sealed environment is greatly improved, and rat and termite-proof sheath material is adopted, so that rat and termite bite of the cable by rats and termites can be avoided.
5. According to the invention, the box body, the two hollow sleeves, the dust collecting groove, the motor, the turntable, the sliding rail, the sliding block and the push plate are used for cleaning the produced cable, so that the cable is vibrated, and impurities on the surface of the cable are cleaned.
